Hi,

now I managed to see my process again. *In short, this is what I found out*:

* when a process is not visible in the jbpm-console, all the other processes in Guvnor's defaultPackage won't be as well
* all my processes that would not show up had loops out of gateway nodes in them. When I removed the gateways, the processes would show up, even if I re-introduced them afterwards
* I did not try if  any change of the semantic of the process would produce that result 

I still have no idea +why+ I can't see them on the first try though, as I completely clean out Guvnor's repository between changes (see below), so the bug you mentioned should not occur.

*Long story*:
In order to find out if my problem was linked to the bug you described, I minimized my process again, this time clearing the Guvnor repository after each change (i.e. stopping JBoss, deleting $JBOSS_DEPLOYMENTS/repository and $JBOSS_TEMP/*, restarting JBoss). After the first change (removing all Gateways), I could suddenly see the task and after re-introducing them, the task was still visible (i.e. in its original version). I tried to manipulate the circumstances of uploading and deploying in order to see why the process was visible, but found none of them had any influence.

Only when I added another process to the repository (already in the initial build), I would consistently see neither of them both. The only difference in the server logs is that in the unsuccessful case, the last log entries are these...

... while in the successful case, before "jbpm.console.directory property not found" would be this line...

> 15:13:27,114 INFO  [stdout] (http--127.0.0.1-8080-4) Loading process from Guvnor: ua.telepark.CustomItemWSTest

... and then several lines with exceptions because I didn't upload a diagram.

As it turned out, I couldn't see the second process even if there was no other process in the repository. But with another process that already worked before these problems began, I could see both. So I did to my second invisible process what I had done to the first: removing and reintroduce the gateways. The result was the same: the process was now visible as well.
